Leg Soreness (Ulcer)
A skin ulcer is a type of wound that develops on the skin. A venous skin ulcer is a shallow wound that occurs when the leg veins don’t return blood back toward the heart the way they should. This is called venous insufficiency.
These ulcers usually form on the sides of the lower leg, above the ankle and below the calf. Venous skin ulcers are slow to heal and often come back if you don’t take steps to prevent them. Veins that become blocked also may cause fluid to pool, leading to these ulcers.
Arterial skin ulcers are less common than venous skin ulcers. They happen when artery disease is present (sometimes in combination with venous disease). These ulcers tend to be extremely painful. They are usually on the toes and feet.
